螺旋CT对甲状腺病变的诊断价值

The Application of Spiral CT to Diagnose Thyropathy

目的探讨螺旋CT对甲状腺病变的诊断价值。方法分析40例甲状腺病变的螺旋CT增强扫描表现。结果Graves病10例，表现为甲状腺弥漫性肿大，轻度均匀强化；桥本氏甲状腺炎6例，表现为甲状腺弥漫对称性肿大，增强密度较正常低；结节性甲状腺肿7例，表现为双或单侧甲状腺弥漫性肿大，内结节低密度灶，强化不明显；甲状腺瘤8例，表现甲状腺内低密度结节影，结节呈环状强化，界清、常囊变；甲状腺腺癌9例，表现为甲状腺内不规则或分叶结节，境界不清，正常腺体破坏或包膜不完整，强化不均，可伴颈部淋巴结或骨转移。结论螺旋CT对甲状腺病变显示清晰，各种病变有一定特征性表现，特别对甲状腺良恶性结节肿物鉴别价值较高。掌握各病种CT表现，重视增强扫描及图像重建，会有助于甲状腺病变诊断与鉴别诊断。

Objective To study the application of spiral CT to diagnose thyropathy Nethod Analysis the change in constrast enhanced CT images of 40 thyropathy cases Results 10 cases of Graves disease, thyroid diffuse intumesce and lightly welldistributed augmentation; 6 cases of Hashimotos thyroiditis, thyroid diffuse symmetrical intumesce, augmentation lower than normal;7 cases of nodular goiter, both or half side thyroid diffuse symmetrical intumesce, low density nodus inside it, no obviously augmentation; 8 cases of thyroid adenoma, low density nodus inside it, the nodus had annular augmentation, clear border and cystic inside; 9 cases of thyroid adenocarcinoma, irregular or lobulated, unclear border nodus inside it, normal glandular organ destroyed and incomplete peplos, uneven augmentation, lymph node of neck metastasis and osseous metastasis. Conclusion Thyropathy were showed clearly in spiral CT images, each had some distinctive appearance, CT images are of good value especially in innocence and malignant differential diagnosis. Master the CT appearance of thyropathy and think highly of enhancement scanning and image reconstruction will help to thyropathy diagnosis.
